successive incr'ementof turn will have a cor responding polnt located on the locus com-,

prising the arc described by the draft tongue end of link 27. The last point of turn on thearc will be determined bythe shortest allowable turn permitted with the present con struction of draft attachment. However, all

i of the successive turning points about which the implement turnsare located considerably to the rear of the tractor and to the rear of the pointof connection of the draft tongue with the tractor, whereby the implement is first madeto turn'in a direction oppositeto the direction in which the tractor turns.

This. action is, of course, supplemented the shiftable hitch member which carries the forward end of the draft tongue laterally along the rear end of the tractor as the tongue is caused to rotate about the end of link as hereinbefore described.-

When the tractor is traveling straight the sliding hitch member to move toward the line of draft, wherethe lateral force .then becomes Iiill It is also to be noted that link 27 and the forward portionof tongue 8 con stitute toggle means which is caused to straighten out by the sliding hitch member wh en the tractor moves in, one direction, and which is caused to be broken to a greater extent by said sliding hitch mechanisni when the tractor turns in, the opposite direction.

The amount of angularity of link 27 with respect to a longitudinal center line passing through the draft tongue and the vehicles when in normal straight forward driving positiommay be varied as desired by using,

links of different lengths under different operating conditions. The length of link used will govern the amountof. movement of the sliding hitch member along the tractor drawbar and .whatever. amount of movement is necessary ,can be best determined from {the particular necessitiesofthe conditions of operation.

Longer links maybe readily employedjby merely shifting the location of yoke 35 along the length of the draft tongue 8 into whatever position is necessaryto accommodate a longer link from that illustrated in Figure 1.' Obviously, the use of a longer link will cause theimplement to turn about a series of points locatedstillfarther to the rearof the I point of connection; of the draft tongue with the tractor than with the use of a shorter link.

The upper and lo er plates 19 and 21, respectively, of the sliding hitch member 17 are also providedlwith suitablyalign' d epen F ingsf36 for the reception-ofga bolt or other means adapted, to belpa'ssed through one of H I the openings -32 in theftractor drawbar 18. This arrangementis merely forsthepurpose of-anchoringthe sli'dinghitchimemb er 17 if to, the drawbar 18; to ,provide a stationary h tch point on the-tractor bn such occasions where the draft tongue guidingmeans is not b slu li e r utilizing a certain type of implement in a Under certain workingjconditions,orwhen field, it maybecome desirable to locate the hitch'mechanisnrin, such aposition on the I tractor drawbar: as to have theshiftable ,9

hitch member 17 normally disposed to one side'iof the center thereof when said'tractor is following a straightpcourse down the field.

Byso doing the implement: wouldbe dis-v tractor. This may, readily beiaccomplished by A adjusting. bracket 25 accordingly along the tractor drawbar by means ofl clamp 26.

It is alsopossible to connect bracket 25 to the drawbar on the opposite side of the-shiftable hitch member, which wouldbring the guid- 7 1 ing means24 on the opposite side of the draft tongue from the position in which said means i cis shown inFig.'1.- Thiswill also increase the amount of adjustability of the guiding means, and when the latter is so located the t hitchconnection Will still function in the capacity for which it was devised, i

Although a preferred"constructionmof hitch connection has been described and illustrated, it is to be understood that such is only by way of example, and that varia tions in the construction of the device may readily be made without departing from the metes and bounds of the present inventioni The invention istherefore not to bejlimited j V to the specific construction, shown but vonly in so far "as may be determined by theap pended claims. l What'I claimgisz a 1.
